title: [The activating effect of antisarcolemmal antibodies on the contractile reactions of the papillary muscles of the rat heart].
abstract: In experiments on the hyperpermeable papillary muscles (PM), we studied the antimembranous antibodies effects on their contractile responses. It has been found that antibodies enhance the amplitude of isometric contraction. Specific antibodies were suggested to induce the release of Ca2+ from the sarcoplasmatic reticulum in the PM of rats.
